Simret 4000
Quick Reference Guide
Always observe safe working procedures when accelerating and stopping the vehicle.
The SIMRET 4000 is operated via its single Click control. The central OK button may be single-clicked,
double-clicked or held-down. The surrounding arrow buttons are used to navigate menus. To switch-on,
hold-down OK for more than one second then release (the instrument will switch off automatically).
BRAKE TESTING
For brake testing, locate SIMRET against a forward bulkhead so that it cannot move under hard braking,
try to position the instrument so that it is as near parallel to the ground surface as possible. The arrow on
the instrument should point forwards. Fit the Pedal Pad by sliding its clip or wrapping its velcro over the
brake pedal,
To proceed with the brake test, click OK on the Brake Testing option in the Start or Main Menu. If the
Bluetooth feature is ON, the instrument will attempt to wirelessly pair with its Pedal Pad. Switch on the Pedal
Pad and wait until the instrument has paired with it, indicated by the light on the Pedal Pad remaining on.
If not successful, single click OK to try again or hold-down and release to abandon. If preferred, connect
the wired Pedal Pad to the DIN connector.
From the Brake Testing Menu select the Plant Name and Test Conditions then single-click on Proceed.
The tester’s name cannot be changed at this point, only from the Main Menu. The Test Reference Number
need not be changed, it will increase by one after each test up to 30,000.
Only click on Proceed if the vehicle is stationary and on a gradient representative of the test course and the
SIMRET is properly located. The instrument will measure the gradient at this point, when prompted press
until it indicates the true gradient of the ground at this point. This compensates for any misalignment
of the instrument. Single-click OK to proceed once the gradient has been set.
Now single-click on the Brake Type to be tested.
The instrument is now armed and the BLUE light will illuminate, safely accelerate to the test speed and
apply the brakes until the vehicle comes to a complete stop. The screen displays the various stages of the
test. Click to Accept or Reject the results. The GREEN pass or RED fail light will illuminate as appropriate.
You will then be asked if you want to do another test.
Please refer to the full instruction booklet for more brake testing
options and more information about brake testing.
